Legend has it that when a person dies, he or she is in a state of great anger, hatred, and fear, and the resentment lingers after death. Some with strong resentment can turn into ghosts, while others can turn into nightmares in the emptiness of dreams.
Nightmares can create dreams, or their own experiences, or their own fantasies.
The Dream Breakers are the natural enemies of Nightmare. They can kill Nightmare in the dreams created by Nightmare.
